Hello, roof with SBS waterproof material bulk density is how much?
Similar to styrene-butadiene rubber, SBS can be in contact with water, weak acid, alkali, etc., with excellent tensile strength, surface friction coefficient, low temperature performance, excellent electrical properties, good processing properties, as the current consumption of the largest thermoplastic Elastomer.
SBS Styrene-based thermoplastic elastomer is the largest yield (more than 70%) of SBCs, the lowest cost and wider application. It is a triblock copolymer with styrene and butadiene as monomer. Plastic and rubber properties, known as the "third generation of synthetic rubber".
As the SBS coil finished with pure asphalt is not the same, the coil includes a variety of surface material weight. The following is the different types and different thickness of the SBS coil unit area weight, due to the need to lap and pave the reinforcement layer, calculate the load in the following unit area weight, the general multiplied by 1.2 coefficient.
